Alex Seropian, the New York Giants have just won the Super Bowl! What are you going to do? I'm going to leave DisneyWorld! Okay, that's probably not how it played out, but GameInformer does report the Bungie cofounder is partying ways with Disney after one year as head of game development. They say an official announcement is expected today, but that the move has been confirmed by Disney. Word is Seropian's position at the Mickey Mouse outfit will be filled by Bill Roper, formerly of Blizzard, Flagship, and Cryptic Studios. Full disclosure: MrsBlue is employed by the Walt Disney Company.
